Configuring the adapter consists of specifying connection and authentication information for each of the connections you want to establish.
How to: Reference: |
In order to connect to the Sybase database server, the adapter requires connection and authentication information. You supply this information using the SET CONNECTION_ATTRIBUTES command. You can:
You can declare connections to more than one Sybase database server by including multiple SET CONNECTION_ATTRIBUTES commands. The actual connection to the Sybase Server takes place when the first query that references the connection is issued. If you issue multiple SET CONNECTION_ATTRIBUTES commands:
You can configure the adapter from either the Web Console or the Data Management Console.
or
from the Data Management Console, expand the Adapters folder.
The Adapters folder opens.
The Add Adapter to Configuration pane opens.
If you are using a Sybase ASE database, click either OCS 15 to connect to the OCS client, which in turn connects to the 15 version of Sybase ASE, or click Sybase ASE 12.5 to connect to the older version of the database.
If you are using a Sybase IQ database, click either OCS 15 to connect to the OCS client, which in turn connects to the 15 version of Sybase IQ, or click Sybase IQ 12.5 to connect to the older version of the database.
The Sybase adapter is under the SQL group folder.
The following list describes the connection attributes for which you can supply values. To complete the attribute declaration, click the Configure button.
Name of the Sybase server to access. It must match an entry in the Sybase interfaces file.
There are two methods by which a user can be authenticated when connecting to a database server:
Primary authorization ID by which you are known to the data source.
Password associated with the primary authorization ID.
Select a profile from the drop-down menu to indicate the level of profile in which to store the CONNECTION_ATTRIBUTES command. The global profile, edasprof.prf, is the default.
If you wish to create a new profile, either a user profile (user.prf) or a group profile if available on your platform (using the appropriate naming convention), choose New Profile from the drop-down menu and enter a name in the Profile Name field (the extension is added automatically).
Store the connection attributes in the server profile (edasprof).
Explicit authentication. The user ID and password are explicitly specified for each connection and passed to Sybase, at connection time, for authentication.
ENGINE SQLSYB SET CONNECTION_ATTRIBUTES server/userid,password
Password passthru authentication. The user ID and password are explicitly specified for each connection and passed to Sybase, at connection time, for authentication.
ENGINE SQLSYB SET CONNECTION_ATTRIBUTES server/
where:
Indicates the adapter. You can omit this value if you previously issued the SET SQLENGINE command.
Is the name of the Sybase server you wish to access.
Is the primary authorization ID by which you are known to Sybase.
Is the password associated with the primary authorization ID.
The following SET CONNECTION_ATTRIBUTES command connects to the Sybase database server named SAMPLESERVER with an explicit user ID (MYUSER) and password (PASS). To ensure security, specify connection attributes from the Web Console, which encrypts the password before adding it to the server profile.
ENGINE SQLSYB SET CONNECTION_ATTRIBUTES SAMPLESERVER/MYUSER,PASS
The following SET CONNECTION_ATTRIBUTES command connects to the Sybase database server named SAMPLESERVER using Password Passthru authentication:
ENGINE SQLSYB SET CONNECTION_ATTRIBUTES SAMPLESERVER/
How to: |
Once connections have been defined, the connection named in the first SET CONNECTION_ATTRIBUTES command serves as the default connection. You can override this default using the SET DEFAULT_CONNECTION command.
ENGINE SQLSYB SET DEFAULT_CONNECTION connection
where:
Indicates the adapter. You can omit this value if you previously issued the SET SQLENGINE command.
Is the connection defined in a previously issued SET CONNECTION_ATTRIBUTES command. If this name was not previously declared, the following message is issued:
FOC1671, Command out of sequence
Note:
FOC1671, Command out of sequence.
The following SET DEFAULT_CONNECTION command selects the database server named SAMPLENAME as the default database server:
ENGINE SQLSYB SET DEFAULT_CONNECTION SAMPLENAME
How to: |
The SET AUTODISCONNECT command controls the persistence of connections when using the adapter for each of the connections you want to establish.
ENGINE SQLSYB SET AUTODISCONNECT ON {FIN|COMMAND|COMMIT}
where:
Indicates the adapter. You can omit this value if you previously issued the SET SQLENGINE command.
Disconnects automatically only after the session has been terminated. FIN is the default value.
Disconnects automatically after each request. Depending on how often the event occurs, the SET AUTODISCONNECT command may result in considerable overhead. Almost all of this overhead is not related to the server. It is related to the operating system and the data source.
Disconnects automatically only after COMMIT or ROLLBACK is issued as a native SQL command.
